The invention discloses a lightweight, low-
odor, low-VOC (volatile organic compounds) and high-temperature-resistant PP (
polypropylene)
honeycomb composite plate with high
impact strength and a methodfor preparing the lightweight, low-
odor, low-VOC and high-temperature-resistant PP
honeycomb composite plate. The lightweight, low-
odor, low-VOC and high-temperature-resistant PP
honeycomb compositeplate sequentially comprises a prepreg
skin layer, a PP honeycomb core layer and another prepreg
skin layer from top to bottom. Heating and cooling composition is proportionally and structurally carried out on glass fibers, micro-spheres and
adhesive powder to obtain the prepreg
skin layers, and a proportion of the glass fibers to the micro-spheres to the
adhesive powder ranges from 39.8:0.6:59.6to 58.8:2.0:39.2. The lightweight, low-odor, low-VOC and high-temperature-resistant PP honeycomb
composite plate and the method have the advantages that the micro-spheres are introduced into ultra-light CMT for the lightweight, low-odor, low-VOC and high-temperature-resistant PP honeycomb composite plate and can be expanded, the
gram weights of the CMT can be integrally reduced, accordingly, the lightweight, low-odor, low-VOC and high-temperature-resistant PP honeycomb composite plate is lightweight under the condition that the forming thicknesses are not changed, and the minimum
gram weight of the lightweight, low-odor, low-VOC and high-temperature-resistant PP honeycomb composite plate can reach 500 g / m<2> while the
gram weights of conventional honeycomb plates are 900 g / m<2> or above.
